: I have a question about the Engine wire harness.

03-24-06, 01:03 AM
I have a 1981 Cadillac Fleetwood that had a 368 engine. I took it out and installed a 1986 5.0 Oldsmoblie engine with a carburator.
I found a 1986 Cadillac Fleetwood at the Junkyard with the 5.0 Cadillac engine with a carburator. It looks exactly like the Oldsmobile engine that I installed in my caddy.
My question is this.
If I where to take the wire harness from the 1986 cadillac at the junkyard, would that harness hook up directly to my firewall or will I have to modify it?

Both harnesses are shaped exactly the same at the firewall.
